 Notable changes
 ===============
 
+Sprout note validation bug fixed in wallet
+------------------------------------------
+We include a fix for a bug in the Zcashd wallet which could result in Sprout
+z-addresses displaying an incorrect balance. Sapling z-addresses are not
+impacted by this issue. This would occur if someone sending funds to a Sprout
+z-address intentionally sent a different amount in the note commitment of a
+Sprout output than the value provided in the ciphertext (the encrypted message
+from the sender).
+
+Users should install this update and then rescan the blockchain by invoking
+“zcashd -rescan”. Sprout address balances shown by the zcashd wallet should
+then be correct.
+
+Thank you to Alexis Enston for bringing this to our attention.

+
+Miner address selection behaviour fixed
+---------------------------------------
+Zcash inherited a bug from upstream Bitcoin Core where both the internal miner
+and RPC call `getblocktemplate` would use a fixed transparent address, until RPC
+`getnewaddress` was called, instead of using a new transparent address for each
+mined block.  This was fixed in Bitcoin 0.12 and we have now merged the change.
+
+Miners who wish to use the same address for every mined block, should use the
+`-mineraddress` option.

+
+
+New consensus rule: Reject blocks that violate turnstile (Testnet only)
+-----------------------------------------------------------------------
+Testnet nodes will now enforce a consensus rule which marks blocks as invalid
+if they would lead to a turnstile violation in the Sprout or Shielded value
+pools. The motivations and deployment details can be found in the accompanying
+[ZIP draft](https://github.com/zcash/zips/pull/210).
+
+The consensus rule will be enforced on mainnet in a future release.
